Specification of Letters Patent. Pa;ented Oct. 10, 1905.

Application filed August 1, 1904. Serial No. 219,076-

To (/J/ 1/71/0711, it may concern:

Be it known that I, Tnouas H. BRADLEY, a

citizen of the United States, residing at \Va- E tertown, in the countyof Jefferson and State of New York, have invented certain new and iprise the number generally in use.

useful improvements in Combination-Tools, of which the following is aspecification.

This invention relates to improvements in i combination-tools designedfor use by carthe employment of which they are enabled to size in aproper manner it requires levers or bars of different thickness andstrength. In my present invention I have shown a lever which is capableof being effectively applied to three different sizes of jacks, whichcom- Another feature of the invention consists in utilizing practicallythe whole length of the bar or lever in operating a jack-screw, becausein so doing 1 gain the advantage of a greater leverage, therebyrendering the work perform certain parts of their work with? greaterconvenience and effectiveness, with a less number of tools to beprovided and cared for, and with a considerable saving in the cost andmaintenance of their working equipment. The invention relatesparticularly to a com- 5 bination-tool comprising a metallic bar or 'le-T The invention consists principally of a steel bar or leversubstantially of the length and weight of a light crowbar, such ascommonly used by carpenters and kindred artisans, and is preferablyforged or formed from a single piece of metal.

The object of the invention is to provide a simple, convenient, light,and durable working tool or implement which consists of combining in onepart a pinch or crow bar having a flat chisel-like projection at one endwith a jack-sorew-operating lever integrally formed on the opposite end.

A prominent feature of the invention consists 1n providlng a comblnationbar or lever, i

one end of which is particularly adapted for use in operatingjack-screws, and wherein I provide a series of shouldered projections,each of which is turned to a diameter and length suitable for insertinginto and operably fitting the transverse holes which pass through theheads of the screws of the different-sized jacks. In order to illustratethe object and value of this feature of my invention.

it is deemed proper at this time to explain j intended that the sectlonsshould vary in that there are several sizes of jack-screws of raising orlowering a heavy load or weight by means of a jack of the class acoi'nparatively light and easy task. Then by providing the pinch or pryfeature to the other end of the bar I complete the combination of ahandy and useful contrivance for the several purposes set forth andclaimed herein.

The invention consists, further, in providing a V-notch in the flatchisel-like end of the bar, forming thereby a claw which may be employedfor pulling or reniovingspikes, &c.

The invention further consists in the constructions and in combinationshereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all ofthe figures, and in which Figure l is a perspective view showing theprominent features embodied in my invention. Fig. 2 is a view showing anelevation of a jack-screw and also my combination-tool applied to thejack as an operating-lever. Fig. 3 is a view of a modified form of thedevice shown in Fig. 1 from which the claw and pinch features have beenomitted.

The bar 2, preferably of steel, is formed at one end with an angularprojection 3, intended principally for use as a pinch or pry bar.

4: represents a claw formed by forging or cutting a V-notch in the endof the projection 3 and is for use in pulling nails or spikes.

6, '7, and 8 represent a series of integral sections or projectionsforged or turned on the upper end of the bar 2. As will be seen byreference to the drawings each of said sections is of an even diameterthroughout its entire length, and each succeeding section is shown andintended to have a substantially increased diameter or thickness. It isalso made and in use and that in operating each i length in about thesame proportion that they increase in thickness. The object in providingseveral diflerent-sized sections is for the purpose of adapting thedevice for use in operating the various sizes of jack-screws in use bycarpenters and other artisans employing such implements. The jack-screwsin common use to-day are practically alike in construction andoperation, and so far as the application of my invention to them isconcerned they are all substantially the same. In all jack-screws, sofar as my knowledge goes,the screw is provided with an enlarged head atits upper end, and through this head transverse holes or sockets areformed, into which the operating-lever is inserted. In applying myinvention the small section 6 at the small end of the bar 2 (which ismade to lit and operate the smallest-sized jack-screw) is inserted intoone of the transverse holes or sockets referred to until it is stoppedby the shoulder 6. Then by turning or swinging said bar to the right orleft the screw is either raised or lowered. The second section 7 isemployed in like manner in operating a jack-screw next larger in size,and the third section 8 may be applied to a still larger one.

Fig. 2 of the drawings shows the bar 2 applied to a jack of intermediatesize, which requires a lever having the diameter of section 7, and theshoulder 7 serves to hold the bar in the position shown. The drawingsshow only three sections, and while that number has been found to besufficient for the general use of such a device still I do not wish tolimit my invention to the specific number of sections as shown, and Imay prefer to increase the number to four or five. The latter feature ofthe invention may also be employed in connection with devices other thanjackscrews and for a variety of purposes not specified and shown.

7 and 8 represent shoulders similar in form and use to the shoulder 6and will be understood without further explanation. The portion of thebar 2 designated by the number 9 is intended to be formed substantiallyas shown on the drawings, so as to conform to the hand of the personusing the said bar for pinching or prying heavy objects or when pullingnails and the like.

10 represents a jack-screw such as employed by builders and otherworkmen.

11 is the head of the screw, and 12 is one of a number of transverseholes or sockets extending through the head 11, into which the operatinglever or bar is inserted.

13 is a swiveled cap or block surmounting the screw-head 11.

14: in Fig. 3 represents a portion of the bar 2 intended for use as ahandle. This is a modified form of the invention and has reference to adevice for operating jack-screws and like devices and wherein the otherfeatures of the combination-tool have been eliminated.

It will be obvious to any one skilled in the art that variousmodifications may be made in the device that I have described and shownwithout departing from the spirit of my invention, and I therefore donot restrict myself to the precise construction herein shown anddescribed.

VVhatI claim, and desire to secure by Letters Patent, is'

The within lever-tool consisting of the bar formed at one end with aplurality of shouldered sections increasing in length and diameter asthey extend toward the central portion of said bar, substantially asshown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
